Title: Manufacture of single crystal film of semiconductor
Inventor: KUSUKAWA KIKUO
IPC: H01L21/203
Filed: 1988-12-07
Abstract: PURPOSE:To obtain a satisfactory crystal over a whole SOI region formed by solid phase epitaxy by a method wherein, when an amorphous silicon film formed on an insulating film is subjected to solid phase single-crystallization epitaxy, a stripe pattern having an angle of 15 deg.-30 deg. against the orientation <110> is used as a seed. CONSTITUTION:A p-type (100) single crystal silicon substrate 1 is subjected to a thermal treatment in a wet oxidizing atmosphere under a temperature about 1,000 deg.C to form an oxide film 2 and the oxide film 2 is selectively removed by photoetching to form a substrate exposing part 3. The substrate exposing part 3 is used as a seed of crystal growth and formed into a stripe pattern having an angle about 25 deg. against the orientation <110> of the substrate 1 surface. Successively, the amorphous silicon film is subjected to a thermal treatment in vacuum for solid phase single-crystallization epitaxy to form a single crystal film 4. Therefore, the crystal is made to grow vertically from the seed 3 of the sample first and then, after the growing crystal crosses over the pattern edge of the oxide film 2, the crystal is made to grow horizontally. With this constitution, a single crystal region having excellent crystallinity can be formed.
